I like Ariel's Grotto for the food, and the fact that the princesses don't arrive until you are almost finished with your meal. When I was there last, they did not rush us at all, and we had a lot of time with the princesses. Plaza Inn does have a lot of great characters, but it is just average buffet food. So I guess you need to decide what your priority is. If you want quality of food, over the number of characters than Ariel's is a good choice. I haven't been to Goofy's Kitchen or Storytellers lately, but I enjoyed them in the past. PCH Grill was a big disappointment to me when I was there about two years ago. The food was fair, but the characters kept ignoring me. I guess they thought a solo guest did not want their attention. So wrong. I left there feeling quite angry that I had to ask for attention from the characters.
